How to customize behaviour of generated services/methods?

[Filson14]

Hi all!

I've got some issue to resolve and wonder if it is possible to clearly develop together with codegen.

I use graphql-codegen typescript-apollo-angular generator in Angular8 project together with GraphQL API.
I need to manipulate requests process to perform some actions right before sending a request and in some cases delay/cancel it.

In another word - it would be something like, when I call watch method from originally generated GQL service, I would like to call my function/method first and then from inside, call original one.

Is there a way to customize services generated by generator? Or to add some decorator/extend base class? I know I can make my own service and pass those GeneratedServices to some methods every time I need to perform request (callback-solution), but it is not a clear solution and can provide a lot of problems.

If my description is not clear I will extend it. Hope to hear something from you, 'cause I don't have another ideas...
Would appreciate any kind of help!

High5!

At the moment, it's not possible to manipulate the generate service with the Apollo-Angular plugin. I can recommend you to either fork it and adjust it to your needs, or create a custom plugin that add the functionality you need.
